spawn data integrity

[c0ncrete]

Should there be instances in the database where there is no spawnentry for a given spawngroup or spawnentries with a combined chance of less than 100%?

I'm just guessing that any spawngroup with less than a 100% combined chance for its individual spawnentries will have the remaining chance assigned to not spawning an npc_type at all until the timer expires again... maybe?

Spawngroups with no spawnentries at all seem like a waste of space. Is there something I'm not grasping?

Examples:

spawngroup 27630 has no spawnentries
spawngroup 16814 has a single spawnentry (id: 16814 npc: 163095) with a 2% chance

not everytying is spawned from the database. some things are spawned from quest scripts in *.pl files. That doesn't mean there aren't orphaned entries though.
